"Aionios is also used of the sin that 'hath never forgiveness,' Mark 3:29, and of the judgment of God, from which there is no appeal, Hebrews 6:2, and of the fire, which is one of its instruments, Matthew 18:8; Matthew 25:41; Jude 1:7, and which is elsewhere said to be 'unquenchable,' Mark 9:43. "The use of aionios here shows that the punishment referred to in 2 Thessalonians 1:9, is not temporary, but final, and, accordingly, the phraseology shows that its purpose is not remedial but retributive." * [* From Notes on Thessalonians by Hogg and Vine, pp. 232,233.]
